New Access Rule Editor - Simplify selection of read/write

Maybe it's just me getting older, but when setting up new access rules I find it quite annoying to play aim and click on the new checkboxes for read and write.

Can you please increase the clickable area?

Or switch to another approach for selecting the permissions? After all, there's only 3 valid options (or combinations), so checkboxes don't seem the natural choice for this.
